SAE 52100 Grade Steel
Manufactured from ultra-clean high-carbon chromium steel (100Cr6), hardened to 60-64 HRC for exceptional fatigue life and resistance to subsurface cracking.
In-House QC & Testing Labs
100% pre-dispatch quality verification performed at our dedicated in-house testing laboratories by qualified QC engineers for dimensional runout, radial clearance, and noise testing.
Precision Class (P0 / P6 / P5)
Standard ABEC-1 (ISO Normal / P0) tolerance with optional P6/P5 precision grades for ultra-low vibration (V2/V3) and high rotational accuracy.
Thermal Stabilization
Dimensionally stabilized for continuous operating temperatures from -30°C to +120°C (standard), with high-temperature synthetic grease available up to +180°C.
Radial Clearance (CN / C3)
Available in Standard Normal Clearance (CN) for steady ambient operating environments or C3 Greater Clearance for thermal expansion.
Global Export & Trade Fairs
Export packaging ready for international supply via Nhava Sheva (JNPT) & Mumbai Air Cargo with upcoming planned participation in premier international trade expos.
Separable Cup & Cone Construction
The Cone (inner ring, rollers, and cage assembly) can be mounted independently from the Cup (outer ring), simplifying assembly and maintenance.
Preloaded Paired Mounting (DB / DF)
Designed for mounting in opposed pairs (Back-to-Back DB or Face-to-Face DF) to withstand combined high radial and bi-directional axial thrust loads.
Through-Hardened & Case-Hardened Steel
High-alloy chromium steel raceways with optimized logarithmic contact profiles to eliminate edge stress under heavy moment forces.
Heavy-Duty Pressed Steel Cage
Standard high-strength pressed steel window cage providing precise roller spacing and lubricant retention across heavy vehicle wheel hubs.
